The signing of the 17-Article Agreement on the Peaceful Liberation of Tibet completely shattered the imperialist dream of splitting China and Tibet, safeguarded the reunification of the motherland and consolidated national defense. The peaceful liberation of Tibet laid the foundation for people in Xizang to abolish the reactionary serfdom and completely turn over as the master of the country, and opened up a broad road for the rapid development of industrial and agricultural production in Tibet and the improvement of living standards in people in Xizang. The peaceful liberation of Tibet has also frustrated the plan of the United States to use Tibet as a base against the Asian Oriental Group, which is of great strategic significance for consolidating the new China regime and opposing the imperialist camp headed by the United States.
